Line of sight and transverse magnetic field from STiC (non-)LTE inversions of the Fe I Hinode data over the sub-field indicated by the dashed green box in Fig. 1. From left to right the columns show the photospheric field at different log τ₅₀₀ depths as specified in the top left corner of each panel, both for LTE (top row) and non-LTE (bottom row) inversions. The maps are of the LOS field (scaled according to the right-hand colour bar), while the blue arrows indicate the azimuth direction, where their hue reflects the horizontal field strength (according to the top colour bar). All panels are colour-scaled between the same values with both LOS and horizontal field strengths clipped to the range wherein 98% of the pixels fall. Bright green contours indicate where the horizontal field is in excess of 5 kG, while the cyan contours in the first column highlight where the Fe I lines are in emission. The coloured plus signs mark the locations for which (non-)LTE profile fits are shown in Fig. 4.
